摘要

After an onsite first time assembly (OFTA) lasting just 2.5 months, Atlanta, GA's newest tunnel boring machine (TBM), dubbed "Driller Mike," made its initial startup on Oct. 13,2016 and ramped up to full production two weeks later. Atlanta's Mayor Kasim Reed and city officials gathered with local and national media to celebrate the occasion. The 3.8 m (12.5 ft) diameter Robbins main beam TBM is now boring the 8-km (5-mile) Bellwood Tunnel after being walked forward 30 m (100 ft) into a starter tunnel. The Bellwood Tunnel path will travel from an inactive quarry and run below a water treatment plant and reservoir before ending next to the Chattahoochee River.
